 I've came across a bug trying to fetch a custom theme
 (http://themeforest.net/item/rebirth-the-wordpress-theme-for-
 churches/1167055) option (see addendum #1). The value was UTF8 value and
 unserialization failed. DB values were imported by the means of SQL query.

 I applied the following fix:
 instead of:
 function maybe_unserialize( $original ) {
         if ( is_serialized( $original ) )  // don't attempt to unserialize
 data that wasn't serialized going in
             return @unserialize( $original );

         return $original;
 }

 I had:
 function maybe_unserialize( $original ) {
         if ( is_serialized( $original ) ) { // don't attempt to
 unserialize data that wasn't serialized going in
         // fix from:
 http://www.php.net/manual/en/function.unserialize.php#76012
         $out = preg_replace('!s:(\d+):"(.*?)";!se',
 "'s:'.strlen('$2').':\"$2\";'", $original );
         return @unserialize( $original );
     }
         return $original;
 }

 and it worked like a charm.

 I also think that it may have some connection to mbstring settings in
 php.ini on the server.
